Summary
Ground deformation indicating volcanic swelling has been observed at Sakurajima since early July 5, 2025. The Kagoshima Meteorological Observatory warns of potential eruptions at the Minamidake summit crater and Showa crater, which could release large volcanic rocks over 1 km and small pyroclastic flows. Ashfall is expected southeast of the craters during specific timeframes on July 5 and 6. Residents and visitors are advised to remain cautious of volcanic ash and small rocks carried by the wind. The volcanic alert level remains at 3, restricting entry to the area. Authorities urge vigilance within a 2 km radius of the craters due to the risk of ballistic volcanic rocks and pyroclastic flows.
